Function Documentation

t8_geometry_lagrange_destroy()

void t8_geometry_lagrange_destroy

(

t8_geometry_c **

geom

)

Destroy a Lagrange geometry that was created with t8_geometry_lagrange_new.

Parameters

[in,out]

geom

A Lagrange geometry. Set to NULL on output.

t8_geometry_lagrange_new()

t8_geometry_c* t8_geometry_lagrange_new

(

int

dim

)

Create a new Lagrange geometry of a given dimension.

The geometry is compatible with all tree types and uses as many vertices as the number of Lagrange basis functions used for the mapping. The vertices are saved via the t8_cmesh_set_tree_vertices function. Sets the dimension and the name to "t8_geom_lagrange_{dim}"

Parameters

[in]

dim

0 <= dimension <= 3. The dimension.

Returns

A pointer to an allocated t8_geometry_lagrange struct, as if the t8_geometry_lagrange (int dim) constructor was called.
